Changing date and time in jpeg files

[andrewm43705351]

Apologies for reposting this question which I'm sure has been asked many times before but I can't seem to find an answer...

The original time and date setting on my camera was wrong for the first 1,000 photos, and i now want to go back to the original jpeg files and change the "Created" dates and times to be correct.

I'm using Lightroom 2 on a Mac, and am able to reset dates and times within Lightroom so the metadata is showing correctly. However when I do a save back to the jpeg file (either individually or in bulk) using the instruction from the manual ("Metadata > Save Metadata to files" or Command + S), the "Created", "Modified" and "Last Opened" dates all appear as the current date and time (i.e. the time the file is saved).

How do I amend the "Created" date and time to be correct in the file please?

That is because the OS Reads the file dates differently than what LR is showing. The OS is showing WHEN they were created, modified, whatever, ON DISK (On your Hard Drive). Not the Capture date/time of the image as recorded in the Metadata.

Thank you. The instructions in the LR manual seem misleading then as i was following instructions to save metadata changes to the file itself (not just the information viewed in LR).

Is there a way to change the creation date/time in the file itself?

You did save it in the Metadata. That is what LR reads. What the OS reads is something different. The OS reads the Creation, Modified, date and time of when it was put on disk and when that file was changed on disk. The OS does not read the metadata like LR does.
